"My vocal cords are healing, but they are not all the way back to normal yet, so my doctors want me to continue to rest my voice," Timberlake wrote in an Instagram post late Wednesday. "They have asked me to hold off on singing until next month. I'm really sorry, I want to be back on the stage and I am doing all I can to get there quickly."

He went on to thank his fans for their understanding, support and love.

"I look forward to coming back stronger than I was before," he said. "More to come on the rescheduled dates."
